Fume hood are devices designed for work with toxic or hazardous chemicals with the effect of safely capturing the harmful gases, vapors, and fumes generated and exhausting them to the outside air. The fume hood is very effective if installed and used properly and maintained in good working order. Fume hoods are not just fixtures but are installed into the ventilation system of a building and so affect the ventilation of the entire building and the exhaust at the stack.

The role of fume hood in the laboratory
The fume hood removes the toxic substances that fly in the air, protects the workers in the laboratory and improves the conditions of the experiment.Use of a high-quality fume hood during an experiment or research prevents the inhalation of toxic substances by the operator.The toxic substances are transferred into the filters in the hood. The air that enters the fume hood enters the filter that removes the harmful substances from the air and returns it to work
Advantages of fume hoods:
• Quiet and efficient work
• Filter toxic substances in the air
• Suitable for any type of work in laboratories. Comes in different and varied sizes.
• Maintains the health of employees
• Easy and quick installation
• Durable, efficient and convenient
• Maintains laboratory equipment and materials themselves
